Filed:

Nov 16, 2005

Appl. No.:

11/282046

Inventors:

Duncan L. MacFarlane - Dallas TX, US
Richard Briggs - Dallas TX, US
Andrei A. Zaremba - Richardson TX, US
Keith D. White - Gainesville FL, US

International Classification:

G01V 3/00

US Classification:

324318, 324319

Abstract:

The present invention relates, in general, to the field of motion tracking, and in particular to join a target in an MRI application. In particular the invention teaches an apparatus and method to track the movement of a target during medical imaging scanning using optical technology. Optical systems record the position and movement of the pattern and are able to perform mathematical analysis of the pattern to determine the positional shift of the patient. Weighted averages, Fourier transforms, Hadamard matrices and cross-correlation of data related to X-Y translation, rotation and scaling of the image of the pattern are used to analyze movement of the subject's head. Feedback related to the movement is provided to the MRI machine which allows for adjustments in focusing coils for real time tracking of the patient's movements during the MRI procedure. As a result, the MRI procedure becomes more accurate as it is adjusted for the patient's movements.

International Classification:

G01V 3/00

US Classification:

324307, 324309

Abstract:

The present invention discloses a method for determining location and movement of a moving object. One embodiment of the method tracks the movement of a target during medical imaging scanning and transmits the position shift to the medical imaging scanning device in real time. The method includes the steps of projecting structured light on the target, receiving the reflection of structured light, converting the received structured light into spatial positions, and transmitting the positional shift to the medical imaging scanning device. The method further includes the step of adjusting the medical imaging scanning device in response to the positional change to increase accuracy.

International Classification:

G01V 3/00

US Classification:

324309, 324307

Abstract:

Apparatuses, systems, and methods for suppression of venous artifacts from superior tagging in flow-sensitive alternating inversion recovery. The systems may include an image capture device and a controller. The controller may be configured to cause the image capture device to perform a labeling experiment, capture a first image of a slice of body tissue, perform a control experiment, and capture a second image of the slice of body tissue. The systems may be configured to perform a ninety (90) degree RF saturation pulse directed to a portion of body tissue that is superior to the first slice of body tissue imaged during at least one of the labeling experiment and/or the control experiment, and to apply a spoiler gradient subsequent to the saturation pulse during at least one of the labeling experiment and/or the control experiment.

International Classification:

G01V 3/00

US Classification:

324318, 324322

Abstract:

The present invention discloses an apparatus and method to track the movement of a target. One embodiment tracks the movement of the patient during medical imaging scanning using optical technology. Optical systems record the position and movement of the target and provide inputs to a processor. The processor is capable of performing mathematical analysis of the movement of the target to determine the positional shift of the patient. Weighted averages, phase correlation, Fourier-Mellin algorithms, and cross-correlation of data related to X-Y translation are used to calculate movement of the target subject. Feedback related to the movement is provided to the medical imaging scanning machine which allows for adjustments in focusing coils for real time tracking of the patient's movements during the procedure. As a result, the medical image scanning procedure becomes more accurate as it is adjusted for the patient's movements.

International Classification:

A61B 5/055

US Classification:

600419

Abstract:

Methods, devices, and systems for creating an MRI image using an orthogonally positioned tagging imaging method for arterial labeling with FAIR. Embodiments of the present methods for creating an MRI image may include positioning a perfusion imaging plane that corresponds to an image target area of an imaging object, and causing an MRI image to be generated that corresponds to a representation of the image target area at the perfusion imaging plane. The perfusion imaging plane may be orthogonal to a direction of inflow from immediately proximal arteries of the image target area.
